The environmental chemistry of selenium in the San Bernard River
(1977)
Samples from the lower San Bernard River, located on the Texas Coastal Plain, were analyzed for selenium by the latest techniques of atomic absorption spectrophotometry. Concentrations as high as 50 ug/l soluble, 20 ug/l ...
Investigation of the development of ultrahigh-strength Portland cement concrete (UHSC) consolidated by statically applied high confining stress systems
(1988)
Large size (12-in. cubes) specimens of ultrahigh-strength portland-cement concrete and mortar were successfully produced by using a high-pressure confining mold (12-million-pound total load capacity) designed, developed, ...
An investigation of asphalt-rubber binders for use in pavement construction
(1985)
Two experimental test roads containing asphalt-rubber interlayers were constructed. Both test pavements were designed as statistical experiments such that future performance analysis could be obtained. Precondition surveys ...
Measurements of pavement condition and performance for Texas highways using sampling techniques
(1979)
Cost-effective, objective performance information obtained on a highway network better enables highway maintenance managers to make informed decisions. Three methods which can be used to obtain such objective information ...
Development and impact of Section 13(c) within the Urban Mass Transportation Act of 1964 on the labor-management structure of Texas Transit Systems
(1985)
