Interim Report on the Significance of Pavement Design and Materials in D-cracking


Book Description

A two-phase program was undertaken to verify, under field conditions, that reducing maximum aggregate particle size can minimize or eliminate D-cracking. This study was carried out also to determine the role of other materials and environmental factors in D-cracking which are not amenable to laboratory study. One phase consisted of repeat pavement surveys of existing pavements to determine whether reducing maximum particle sizes has alleviated D-cracking. The other, primary, phase consisted of monitoring the performance of a test road near Vermilion, Ohio, using visual inspections and moisture measurements and examinations of concrete cores.

D-cracking of Concrete Pavements


Book Description

This synthesis will be of interest to pavement designers, materials engineers, maintenance engineers, and others concerned with design, construction, and maintenance of portland cement concrete pavements. Information is presented on the causes of and potential means for minimizing D-cracking of concrete pavements. In certain areas of the country, the coarse aggregates used in concrete pavements are susceptible to disintegration from repeated freezing and thawing. This report of the Transportation Research Board describes the mechanisms of D-cracking, summarizes known materials-acceptance and design techniques that can minimize D-cracking of new pavements, and describes rehabilitation techniques for existing pavements.







An Evaluation of the Cost Effectiveness of D-cracking Preventive Measures


Book Description

D-cracking has long been a serious problem in the deterioration of concrete pavements in severe weather climates. After much research, the mechanics and variables involved in the destructive forces of concrete D-cracking are becoming known. This study focuses on these variables that include analysis of the cost effectiveness in using certain preventive measures to reduce premature deterioration of concrete pavement due to D-cracking.
