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 ...

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 ...

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 ...

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 ...

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 ...

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 ...

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 ...

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 ...

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 ...

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 ...
