Testing and Evaluation of Used Automobile Tires and Recycled Tire-Derived Materials for Low-Cost Crash Cushions
Publisher: American Society of Civil Engineers
Abstract: Approximately 30% of all vehicle related fatalities that occur each year are caused by a single vehicle leaving the road and striking a fixed object; the most common objects struck being trees, guardrails, and utility ...
Fracture and Tensile Characteristics of Asphalt-Rubber Concrete
Publisher: American Society of Civil Engineers
Abstract: Fracture and tensile characteristics of asphalt concrete mixtures affect the structural performance of pavements, particularly under low-temperature conditions. This paper reports a study of the tensile and fracture ...
Estimation of Pavement‐Layer Moduli using Nonlinear Optimization Technique
Publisher: American Society of Civil Engineers
Abstract: Falling Weight Deflectometer (FWD) testing is used for nondestructive structural evaluation of existing pavements. The deflection data from FWD can be used for estimation of layer moduli by an iterative technique. In the ...
Cross Tensioned Concrete Pavement
Publisher: American Society of Civil Engineers
Abstract: The deterioration of Portland cement concrete pavement is most often due to intrusion of water into the pavement system as well as due to inferior performance of the transverse joints. The infiltration of surface runoff ...
Field Verification of Superpave Dynamic Modulus
Publisher: American Society of Civil Engineers
Abstract: In the mechanistic-empirical pavement design guide, prediction of flexible pavement response and performance needs an input of dynamic modulus of hot-mix asphalt at all three levels of hierarchical inputs. This study was ...
Performance-Related Specifications for PCC Pavements in Kansas
Publisher: American Society of Civil Engineers
Abstract: Statistical specifications for highway construction provide the means to measure important quality control attributes and ensure their compliance. The pay adjustments in these specifications reflect the amount of pay ...
Effect of Curing on Roughness Development of Concrete Pavements
Publisher: American Society of Civil Engineers
Abstract: This paper deals with the results of a study on the effect of curing on as-constructed smoothness and subsequent roughness development of portland cement concrete pavements (PCCP) in Kansas. Ten test sections on five newly ...
Cracking Resistance Evaluation of Mixtures with High Percentages of Reclaimed Asphalt Pavement
Publisher: American Society of Civil Engineers
Abstract: Incorporation of high quantities of reclaimed asphalt pavement (RAP) in new asphalt pavement construction is a contemporary approach for promoting sustainable roadway systems. Many highway agencies, however, have reported ...
Estimation of Remaining Service Life of Flexible Pavements from Surface Deflections
Publisher: American Society of Civil Engineers
Abstract: Remaining service life (RSL) has been defined as the anticipated number of years that a pavement will be functionally and structurally acceptable with only routine maintenance. Usually RSL is computed from pavement condition ...
Practical Issues in Implementation of Mechanistic Empirical Design for Concrete Pavements
Publisher: American Society of Civil Engineers
Abstract: This study was undertaken to locally calibrate and implement the models for a mechanistic-empirical design guide (MEPDG) for jointed plain concrete pavement (JPCP) sections. Twenty-two newly constructed JPCP projects were ...
