Book excerpt: "Providing adequate drainage to a pavement system has been considered as an important design consideration to prevent premature failures due to water related problems such as pumping action, loss of support, and rutting, among others. As a result, permeable bases with drainage efficiency and structural stability characteristics have been widely used by several state DOTs in the design and construction of pavements. The Ohio Department of Transportation (ODOT) has adopted several types of materials specification for use as permeable bases: (a) unbounded base materials including: 308-IA, 307-NJ, and 30-7-CE types, (b) stabilized base materials including: cement and asphalt treated base types. The main objective of this research is to study the performance of different permeable base materials used by the Ohio Department of Transportation (ODOT). Field monitored data combined with laboratory result data are used to determine the drainage efficiency of different permeable base materials used by ODOT. Analysis using Multi-Layer Linear Elastic Analysis (MLEA) and data obtained from field backcalculated resilient modulus are used to predict pavement service life for pavement section with different permeable base materials. To account for effect of environmental factors in pavement design, the Enhanced Integrated Climatic Model was used to predict temperature, moisture and frost depth data at the Project Site, Ohio. Comparisons were made between the predicted and measured moisture contents and temperature along the depth of pavement sections as well as frost depth at different times during the simulation period. Analysis was conducted to study the characterization of permeable base materials in the new Mechanistic-Empirical Pavement Design Guide (MEPDG). Flexible pavement designs and performance derived from the MEPDG approach are compared for different base materials over a range of asphalt concrete layer thicknesses, base materials, subgrade and other material properties. As shown consistently in this study, the impact of unbound materials layer on performance as predicted by the MEPDG methodology is less pronounced than the impact of asphalt concrete layer. Based on the concept of effective stress of unsaturated soils, the matric suction of soil was shown to be an important state variable for predicting moisture-dependent resilient modulus of cohesive soils. A prediction model is proposed and shown to be capable of predicting the resilient modulus of cohesive soils over a range of stress states and water content. The accuracy of the proposed model is validated against experimental data of A-4 and A-6 soils as well as other data available in the literature. Movement of water through the different pavement sections at the project site was modeled by the finite element method (FEM). FEM modeling taking into consideration of both saturated and unsaturated flow appears to be capable of predicting water content regime in pavement layers (base, subbase, and subgrade), as demonstrated in this study when comparing with field moisture monitoring results. Accurate simulation of the boundary and initial conditions, together with representative soil water characteristic curves and the hydraulic conductivity curves for each material, resulted in accurate predictions that match with the measured field results."--Abstract.

Available in PDF, EPUB and Kindle. Book excerpt: The adverse effects of entrapped water within a pavement system are generally well known. In an attempt to reduce or eliminate the detriment, the West Virginia Department of Highways designed and constructed its first major project which utilized a free draining concept. The free draining system used is basically a 4 inch bituminous stabilized, open graded base course, underlain by engineering lateral aggregate filled fabric underdrains. This final report documents the design, construction, and completion of a three year testing and evaluation program of the experimental pavement.

This book was released on 2009 with total page 263 pages. Available in PDF, EPUB and Kindle. Book excerpt: "It is a well recognized fact that pavements with poor subsurface drainage properties prematurely exhibit distress and have higher life-cycle cost. Thus, providing adequate subsurface drainage in a pavement system to remove the infiltrated moisture in a timely manner is an important design consideration. Currently, Ohio Department of Transportation (ODOT) accepts several types of materials specifications for use as drainable base materials. They are ODOT 307 (NJ, IA, and CE), ODOT 308 (asphalt treated), and ODOT 306 (cement treated). However, the effectiveness of these base materials in actual service has not been conclusively established in previous ODOT studies. Consequently, a research project, so-called ATB-90, was initiated in 2002 to provide additional data to asses the merits of the drainable bases in the asphalt pavement. At the present time, most of the current drainage criteria have been developed on the basis of describing water flow in saturated conditions. Yet this could happen in a very limited circumstance and time duration. In this study, a transient analysis using SEEP/W program was conducted to simulate water flow in a flexible pavement system. A new predictive equation along with design charts for estimating the time required to drain 50 percent saturation were developed by utilizing the results of SEEP/W analysis. The predictive equation could be used to design a flexible pavement system for effective subsurface drainage."--Abstract.
