Download or read book Pavement Subsurface Drainage Systems written by Barry Rodney Christopher and published by Transportation Research Board. This book was released on 1997 with total page 56 pages. Available in PDF, EPUB and Kindle. Book excerpt: This synthesis will be of interest to geologists; hydrologists; geotechnical, pavement, construction, and maintenance engineers; and researchers. State department of transportation (DOT) program managers and administrators will also find it of interest. The synthesis describes the current state of the practice for the design, construction, and maintenance of pavement subsurface drainage systems. It provides information on the positive effects of good subsurface drainage and the negative effects of poor subsurface drainage on pavement surfaces. This report of the Transportation Research Board presents data obtained from a review of the literature and a survey of the state DOTs. It is a supplemental update to NCHRP Synthesis of Highway Practice 96, Pavement Subsurface Drainage Systems (1982). The synthesis provides a supplement to design issues not found in Synthesis 96, but faced by current designers, e.g., type and quality of aggregate, compaction requirements for open-graded aggregates, asphalt and cement binders, and use of geosynthetics. In addition, it describes the effects of design, construction, and maintenance decisions on the performance of pavement subsurface drainage systems.

This book was released on 2005 with total page 26 pages. Available in PDF, EPUB and Kindle. Book excerpt: Following the recommendation of the Virginia Transportation Research Council's Pavement Research Advisory Committee, this project was initiated to determine the effectiveness of including subsurface drainage systems in pavements in Virginia. The researchers sought to determine the effectiveness of these systems by conducting a literature review and by comparing the strengths of pavement sections with and without a subsurface drainage layer in a limited field investigation involving two pavement structures in Virginia. The strength of the pavement structure was analyzed using the falling weight deflectometer. The researchers concluded that the drainage layer appears to affect positively the in-situ subgrade resilient modulus and the in-situ structure number. Further, inclusion of a properly constructed drainage layer does not adversely affect the deflection of a pavement and thus does not introduce a weakness into the pavement structure. However, the condition of the outlet pipes appears to be of high importance. The researchers recommend that tests with additional sites be conducted in the spring when the subgrade moisture is expected to be highest; that the Virginia Department of Transportation (VDOT) develop a maintenance program to maintain functioning drainage outlet pipes; and that VDOT continue the practice of constructing subsurface drainage features on high-priority pavements. In 2005, VDOT anticipates spending approximately $45 million on resurfacing interstate and primary roadways. According to the literature review, the average service life of flexible pavements (time between successive rehabilitation efforts) is approximately 9 years. Including subsurface drainage features offers a 4-year extension of service life (a 44% extension). Thus it can be approximated that the current practice of including subsurface drainage features is saving VDOT approximately $20 million per year. However, the amount of this cost savings may not be fully realized if drainage outlet pipes are blocked or partially blocked. As reported in the literature review, nonfunctioning drains accelerate pavement deterioration and thus may actually shorten the service life of pavement structures.

Available in PDF, EPUB and Kindle. Book excerpt: "The behavior of flexible pavements under traffic and environmental loading can be significantly affected by subsurface conditions. Inadequate support conditions under the surface can lead to excessive pavement deformations, often leading to structural and functional failure. This research effort focused on assessing the effects of base/subbase and subgrade layer conditions on flexible pavement behavior. The results of this study are presented in the form of two journal manuscripts. The first manuscript focuses on utilizing pavement structural and functional evaluation data in making pavement rehabilitation decisions. Visual distress surveys and Falling Weight Deflectometer (FWD) testing are often carried out by agencies as a part of their pavement preservation programs. Although back-calculation of individual layer moduli from FWD data is a common approach to assess the pavement's structural condition, the accuracy of this approach is largely dependent on exact estimates of individual layer thicknesses. Considering the lack of pavement layer thickness information for all locations, this study used Deflection Basin Parameters (DBPs) calculated from FWD test data to make inferences regarding the structural condition of individual pavement layers in conventional flexible pavements. The adequacy of DBPs to assess the structural condition of individual pavement layers was assessed through Finite-Element (FE) Modeling. Subsequently, four selected pavement sections in the state of Idaho were analyzed based on this method to recommend suitable rehabilitation strategies. The second manuscript focused on studying how improvements to subsurface layers can affect the flexible pavement behavior over expansive soil deposits. A recently completed research study at Boise State University investigated a particular section of US-95 near the Idaho-Oregon border that has experienced significant differential heave due to expansive soils. Laboratory characterization of soil samples indicated the presence of highly expansive soils up to depths of 7.6 m (26 ft.) from the pavement surface. Through subsequent numerical modeling efforts, a hybrid geosynthetic system comprising geocells and geogrids was recommended for implementation during pavement reconstruction. This research effort focused on evaluating the suitability of polyurethane grout injection as a potential remedial measure for this pavement section. Laboratory testing of unbound materials treated with a High-Density Polyurethane (HDP) demonstrated that resilient modulus and shear strength properties could be improved significantly. Finite Element modeling of the problematic US-95 pavement section indicated that depending on the treated layer thickness, the differential heave magnitude can be reduced significantly, presenting polyurethane injection as a potential nondestructive remedial measure. ."--Boise State University ScholarWorks.
