Evaluation of the filler effects on fatique cracking and permanent deformation of asphalt concrete mixtures
(Texas A&M University, 1997)
The addition of hydrated lime to asphalt has shown to be beneficial with an improvement in the Theological properties of the binder, as well as resistance to permanent deformation (rutting) and fatigue cracking of asphalt ...
Biodegradation of octahydro-1,3,5,7-tetranitro-1,3,5,7-tetrazocine (HMX)
(Texas A&M University, 1997)
Since World War II, octahydro-1,3,5,7-tetranitro-1,3,5,7-tetrazocine (HMX) has been one of the most widely used explosives. Consequently, many munitions facilities and other related sites have been contaminated with HMX ...
A study of immobilization of four heavy metals by solidification/stabilization with portland cement
(Texas A&M University, 1994)
Two sites were established in Harris County, Texas, to relate seasonal saturation to soil morphology, micromorphology, soil reduction potential (Eh), and iron phases; and to test a,a'-dipyridyl dye for field identification ...
Evaluation of design and operating speeds for crest vertical curves with limited sight distance
(Texas A&M University, 1994)
The Puerto Colon field is located in the Putumayo basin in southern Colombia, South America, and is operated by Empresa Colombiana de petroleos (ECOPETROL), which is the national oil company. The field produces from the ...
A systematic approach for characterizing waves in a model basin
(Texas A&M University, 1994)
This research study focused upon the development of a general methodology to characterize regular and random waves in a large model basin. The objectives of the study were to both identify and quantify the various ...
Development of criteria for fatigue repairs in bridge girders damaged by out-of-plane distortion
(Texas A&M University, 1994)
Numerous highway bridge girders across the United States have experienced fatigue cracking due to repetitive out-of-plane distortion at unstiffened web gaps caused by poorly designed diaphragm connection details. Due to ...
Nitrogen and chlorpyrifos in surface water runoff from a golf course
(Texas A&M University, 1995)
In recent years, the turfgrass industry has received a great deal of criticism for its abundant use of chemicals on golf courses and the potential risk that this poses to the surrounding environment. With the limited supply ...
A comparison of the fracture properties of conventional and polymer-modified two-layer asphalt concrete overlay systems
(Texas A&M University, 1996)
The problem of reflection cracking through the conventional asphalt concrete overlays has increased the need to find new materials which could resist cracking or fracture more effectively. It is for this reason that polymers ...
A comparison of trip production rates developed from two types of travel survey diaries
(Texas A&M University, 1996)
In recent years, two types of travel survey diaries have been used to collect travel behavior data for transportation planning: travel diaries and activity diaries. In the travel diary, respondents are prompted to respond ...
In-place engineering properties of recycled and stabilized pavement layers
(Texas A&M University, 1997)
1.0INTRODUCTION Now that most of the new road construction in the United States is complete, the major emphasis has switched to maintaining those roads. The focus of many of Texas districts in the Texas Department of ...
