Mechanistic characterization of thin asphalt overlays for pavement preservation
… concrete (AC) overlays are generally used as a preservation treatment for rigid and flexible pavements to improve ride quality, extend service life, and reduce noise levels on pavements. However, compared to the conventional methods of mechanistic analysis, analyzing thin AC overlay is …

Evaluation of the performance of polyurethane foams in rigid pavement preservation
After several years of service, concrete pavement slabs tend to settle due to weak subgrade or erosion of the subgrade soil. Different treatment techniques have been used to rectify the problem. In recent years, high-density polyurethane (HDP) foams were introduced on concrete pavements after their …

Comprehensive investigation of using tire-derived aggregate in chip seal subjected to various traffic and environmental conditions
… one of the most cost- and performance-effective pavement preservation treatments commonly used in the United States. Using crumb rubber obtained from scrap tires as a partial or full replacement for mineral aggregate has been proposed as a sustainable solution to reduce the negative environmental …

Durable high early strength concrete
… reconstruction of a two-lane concrete pavement costs between $0.8 and $1.15 million dollars per lane mile. High early strength Portland cement concrete pavement (PCCP) patches are widely used in pavement preservation in Kansas due to the ability to open to traffic early. However, these …

Refining Particle Size Specification for Asphalt Emulsion
<p>Pavements begin to deteriorate as soon as they are constructed, and traffic is released. The rate at which a pavement deteriorates depends on the material quality, the environment, and the loads carried. To properly preserve pavements and extend their life, various pavement preservation …

District Level Preventive Maintenance Treatment Selection Tool for Use in Virginia
… to improve network condition by retarding future pavement deterioration. The Virginia Department of Transportation uses its pavement management system to determine maintenance targets for each district. The districts then use these recommendations to select pavements that will receive maintenance …

Model development and validation of bituminous-based crack sealants
A wide spectrum of sealant types commonly used in the United States were installed in eight different test sites using two types of sealing treatment techniques. The performance of sealants was monitored after each winter for three years to determine a performance index (PI) consisting primarily of …
