the available methods for predicting mechanical characteristics of pavement layers are categorized into two general groups, destructive and non-destructive. in destructive method, using coring and pavement subgrade and performing necessary experiments on them, the quantities of layers properties will be identified. in non-destructive method, the attained deflection is measured by applying the l...

This study explored the feasibility of lignin based biofuel co-product (BCP) for subgrade soil stabilization, and more specifically, its impact on Hot-Mix Asphalt (HMA) pavement performance using the Mechanistic-Empirical Pavement Design Guide (MEPDG). The HMA pavement systems with BCP stabilized subgrade under different traffic and climate conditions were modeled using mechanistic based damage...

The three major distress conditions affecting the performance of asphalt pavements are permanent deformation or rutting, fatigue or load associated cracking, and low temperature or thermal cracking. In an earlier technical topics article (Fall, 1998), we examined the causes of fatigue cracking and the importance of good compaction during construction to help minimize this type of distress. In t...

The cold in-place recycling (CIPR) is a process where the existing bituminous pavement is recycled without application of heat. In CIPR process the scarified material from the existing pavement is crushed to the required gradation and binder in cold form (emulsion or cutback or foamed bitumen) is added. Externally acquired Reclaimed Bituminous Pavement (RBP) or fresh aggregates are also added d...

Active and send-active suspensions have been evaluated for application on tractor/semi-trailer trucks using a pitch plane simulation model called "VESYM". VESYM is a fully nonlinear time domain simulation model. This paper reviews the effect of alternative heavy truck suspensions on pavement damage by using the flexible pavement simulation program "VESYS". It is shown that by estimating axle ti...

Soil surface roughness (SSR) is one of the important factors in wind and water erosion studies and control. Several parameters such as surface rock fragments influence SSR. Main objectives of this paper are to study and compare (Allmarass) random roughness (RR) and tortuosity (Tb) indices in coarse, medium and fine grain plains of Yazd-Ardakan and investigate the relationship between indices an...

As one type of pavement distresses, potholes are important clues indicating structural defects of the asphalt road, and accurately detecting these potholes is one of important tasks for determining proper strategies of asphalt-surfaced pavement maintenance and rehabilitation. However, manually detecting and evaluating methods are expensive and timeconsuming. Thus, several efforts have been made...
