OVERLAY DESIGN AND REFLECTION CRACKING ANALYSIS FOR RIGID PAVEMENTS--VOL. 1. DEVELOPMENT OF NEW DESIGN CRITERIA
Fatigue cracking and reflection cracking criteria were developed and incorporated into a design procedure for flexible and rigid overlays of rigid pavements. Linear elastic layered theory is the basic model used to compute stresses and strains in the pavement system, which are then input to the fatigue and reflection cracking models. The fatigue criteria developments resulted from analyses of the performance of rigid pavements at the AASHO Road Test. A regression analysis was performed to obtain a fatigue equation relating stress and wheel load repetitions prior to Class 3 and 4 cracking. The effects of voids beneath the pavement as well as the condition of joints are also considered in the fatigue criteria. The reflection cracking criteria developed resulted from a study of the mechanics of reflection cracking and literature reviews. Mechanistic equations were derived and incorporated into an analysis model for use in design. /Author/
