Sealing cracks in flexible pavements interim report I - flexible pavement crack sealing practices and research approach
(1977-2)In response to a request from the Research Division, a research proposal entitled "Sealing Cracks in Flexible Pavements" was presented to the Oklahoma Department of Transportation in February, 1976. This proposal was for ... -
Sealing cracks in flexible pavements interim report II - crack dynamics field study
(1979-5)The first interim report on Project 77-02-3. "Sealing Cracks in Flexible Pavements", was submitted to the Oklahoma Department of Transportation (ODOT) in February, 1977 (1). This report contained a review of literature on ... -
Sealing cracks in flexible pavements interim report III - laboratory tests of asphalt sealants
(1979-5)A survey of literature pertaining to materials and methods of sealing highway pavement cracks indicated a scarcity of information and a lack of standard testing procedures for asphalt pavement crack sealants. Therefore, ... -
SELECTION OF LONG LASTING REHABILITATION TREATMENT USING LIFE CYCLE COST ANALYSIS AND PRESENT SERVICEABILITY RATING
(2015-10)A wide range of variables influence the selection strategy for rehabilitation and maintenance of pavements. The focus of this study is to conduct a project-level evaluation of high traffic volume asphalt-surfaced pavements ... -
Semiactive vibration absorbers (SAVA) at the I-35 Walnut Creek bridge (FHWA-OK-97-08) 2125
(1997-8)The project was undertaken to develop and field test an automatically controlled bridge mounted vibration absorber. The system, referred to as a semiactive vibration absorber (SAVA) consists of a hydraulic cylinder coupled ... -
SETTLEMENT BEHAVIOR OF COMPACTED OKLAHOMA SOILS (FHWA-OK 02(03) 2152)
(2003-2)Numerous highway embankments experience post-construction settlement problems, such as bridge approach settlement that results in the "bump at the end of the bridge." One of the causes may be wetting-induced collapse ... -
Shrink and swell of excavated earth materials (FHWA-OK-83-01) 236
(1983-1)This study is an attempt to determine from laboratory tests the shrink or swell characteristics o f excavated pedological soils. Twenty-six benchmark soils o f various particle size classes were selected for study. It was ... -
Silane chemical protection of bridge decks (FHWA-OK-86-4) 2709
(1986-12)This report describes the performance of chemical alkyltrialkoxysilane products and their ability to protect bridge structures from moisture, chloride ingr??ssion, and corrosion of reinforcing steel. As a result of the ... -
Silane penetrating waterproofing sealers (FHWA-OK-96-09)
(1996-11)The Oklahoma Department of Transportation has been applying silane penetrating water sealers since the late 1970' s to prevent the intrusion of chloride contaminated water in bridge decks. This contaminated moisture causes ... -
