This book was released on 1992 with total page 40 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report presents the results of a literature review investigating geogrid reinforced base courses for flexible pavements for light aircraft and the design of a geogrid test section for field testing the validity of potential geogrid reinforcement results. The literature review included related areas such as geogrid ballast reinforcement for railroad track bed, reinforcement for aggregate surfaced pavement and reinforcement for flexible pavements. Based on the literature review, geogrids have application in ballast reinforcement for railroad track bed and in reinforcement for aggregate surfaced pavements. Full-scale field tests have verified that for subgrade CBR strengths of 1.5 to 5.0, geogrid reinforced aggregate surfaced pavements can carry about 3.5 times more traffic repetitions than equivalent nonreinforced pavements before a 1.5-in. rut depth is reached. The improvement mechanisms for geogrid, reinforced aggregate layers, are known and both laboratory and analytical studies indicated that geogrid reinforcement of a regate bases can improve flexible pavements performance.

This book was released on 2016-09-15 with total page 877 pages. Available in PDF, EPUB and Kindle. Book excerpt: This compendium gathers the latest advances in the area of Accelerated Pavement Testing (APT), a means of testing full-scale pavement construction in an accelerated manner for structural deterioration in a very short term. Compiling novel research results presented at the 5th International Conference on Accelerated Pavement Testing, San Jose, Costa Rica, the volume serves as a timely and highly relevant resource for materials scientists and engineers interested in determining the performance of a pavement structure during its service life (10+ years) in a few weeks or months.

Available in PDF, EPUB and Kindle. Book excerpt: Bearing Capacity of Roads, Railways and Airfields includes the contributions to the 10th International Conference on the Bearing Capacity of Roads, Railways and Airfields (BCRRA 2017, 28-30 June 2017, Athens, Greece). The papers cover aspects related to materials, laboratory testing, design, construction, maintenance and management systems of transport infrastructure, and focus on roads, railways and airfields. Additional aspects that concern new materials and characterization, alternative rehabilitation techniques, technological advances as well as pavement and railway track substructure sustainability are included. The contributions discuss new concepts and innovative solutions, and are concentrated but not limited on the following topics: · Unbound aggregate materials and soil properties · Bound materials characteritics, mechanical properties and testing · Effect of traffic loading · In-situ measurements techniques and monitoring · Structural evaluation · Pavement serviceability condition · Rehabilitation and maintenance issues · Geophysical assessment · Stabilization and reinforcement · Performance modeling · Environmental challenges · Life cycle assessment and sustainability Bearing Capacity of Roads, Railways and Airfields is essential reading for academics and professionals involved or interested in transport infrastructure systems, in particular roads, railways and airfields.

This book was released on 2017 with total page 4 pages. Available in PDF, EPUB and Kindle. Book excerpt: This standard practice provides guidance to pavement designers interested in incorporating geosynthetics for the purpose of reinforcing the aggregate base course of flexible pavement structures. Geosynthetic reinforcement is intended to provide structural support of traffic loads over the life of the pavement. For the purpose of this guide, base reinforcement is the use of a geosynthetic within, or directly beneath, the granular base course. When referring to geosynthetics, the discussion is limited to geotextiles, geogrids, or geogrid/geotextile composites.

This book was released on 2016 with total page 125 pages. Available in PDF, EPUB and Kindle. Book excerpt: An experimental laboratory program to assess the effectiveness of biaxial and triaxial geogrid-reinforced flexible pavements to reduce roadway section was carried out. Six laboratory tests were conducted using a steel cylindrical mold with dimensions of 1.8 m (6 ft) in diameter and 2.1 m (7 ft) in height. The studied reinforced and unreinforced (without geogrid) sections consisted of a locally-obtained subgrade with a minimum thickness of 1.5 m (5 ft) and an asphaltic surface course of 7.6 cm (3 in). The base thickness of three tests was 30.5 cm (12 in) while for the other three tests used base thickness of 40.6 cm (16 in). A layer of biaxial or triaxial geogrid was placed at the mid-depth of aggregate base course for the tests with 40.6 cm (16 in) of aggregate base layer. For the tests which the base layer was 30.5 cm (12 in), the geogrid was placed at the subgrade-base interface. The instrumentations included pressure cells placed at different locations of the test sections, foil strain gauges installed on the ribs of geogrids, and LVDT placed on top of the loading system. These devices were connected to a data acquisition system. A hydraulic actuator provided 40 kN (9 kips) cyclic load through a 305 mm (12 in) circular steel plate at a frequency of 0.77 Hz. The repeated loading was continued for at least 3 million cycles for each test. Performances of biaxial-reinforced and triaxial-reinforced sections were compared with that of companion unreinforced sections. Test results revealed that inclusion of both biaxial and triaxial geogrids in flexible pavement reduced the surface rutting and vertical stresses in the subgrade-base interface. For the studied geogrid-reinforced pavement sections, no tensile strain was experienced by the strain gauges installed on the ribs of the geogrids. The vertical pressure at the center of subgrade-base interface reduced by an average of 18 and 24% for biaxial and triaxial geogrid-reinforced pavement sections, respectively. Using the
