This study is primarily an evaluation of the effectiveness of "Reclamite" when used as a sealant material for reflection cracks. A secondary objective was to determine the performance of our presently used material - cationic emulsified asphalt (RS-3K) and compare the results to those obtained with "Reclamite". This study was limited to and concern

The effects of high temperature on psychomotor performance and physiological function were studied on male pilots (age 30-51) holding a current medical certificate. A total of 41 runs were made at neutral (23.8C (75F), or hot (60.0C (140F), 71.1C (160F)) temperatures with low humidities (less than 20 mm. Hg at 60.0 and 71.1C). Heart rate (ECG), dee

The presence of unstable cohesive soils is a constant problem in highway construction in Louisiana. An intimate mixture of soil and lime has been proven effective in improving the quality of these soils and lending stability to them. Economic considerations, however, make mixing of the soil and lime, by conventional methods, to the depths required

In 1945, T.C. Powers showed that increased frost resistance of air-entrained concrete was largely a result of the size and spacing of air voids in the cement paste. By considering the hydraulic pressures which may accompany the freezing process, he proposed that the maximum average distance from a point in the paste to the nearest air void be no gr
