Evaluation of asphalt pavements construction practice in West Virginia
Construction practice is a key factor in building high quality pavement. Unfortunately failure and distresses frequently develop shortly after construction. These distresses may be due to the contractors failing to follow the guidelines and specifications. Monitoring pavement construction provides …

RELATING RISKS TO PAY FACTORS FOR HIGHWAY PAVEMENTS THROUGH MONTE CARLO SIMULATION
… for the acceptance of highway materials and pavement construction. The parameters of these statistical acceptance plans are specified based on engineering judgment and may result in a high level of risk to both agency and contractor. In order to appropriately apply such specifications to the …

Comparison of LTPP-Bind V3.1 and MEPDG for the Selection of Binder Grades
Binders for five analysis locations and two pavement designs were selected using the LTPPBind V3.1 software. The recommended binders were then refined to meet realistic constraints of pavement construction in West Virginia. The performance of pavements with the selected binders, pavement structures …

Value Concept for Developing Construction Pay Schedules With Application to Asphalt Paving
… a rational procedure for the establishment of pavement construction pay adjustment schedules. A rational procedure was defined as one that would reflect the impact of construction variability on the expected life of the pavement. The procedure was required to consider both the mean and the …

Development and implementation of comprehensive regionalized pavement life-cycle assessment
… (LCA) to evaluate the environmental impacts of pavement systems is a topic that stakeholders in academia, industry, and government have actively engaged with in the last two decades. The LCA methodology aims to provide quantitative environmental metrics such as energy consumption and greenhouse …

Investigation of cracking resistance of recycled Superpave mixtures
… has become increasingly popular for asphalt pavement construction. Although reclaimed asphalt pavement (RAP) and recycled asphalt shingles (RAS) are typically used in hot-mix asphalt, increasing the amount of RAP and RAS materials increases the potential for premature pavement distresses, …

Life cycle assessment of concrete pavements : impacts and opportunities
The concrete pavement network in the United States plays a crucial role in the economy by enabling the transport of people and goods, but it also leads to resource consumption and environmental impacts. This thesis is fundamentally motivated to reduce the impact that concrete pavements have on …

Permanent Deformation Behaviour of Unbound Granular Materials in Pavement Constructions
… in the unbound granular layers (UGL) in pavement constructions under consideration of the seasonal effects. From this data a serviceability limit line (plastic shakedown limit) stress boundary for the unbound granular materials (UGM) was defined for different moisture contents. Below this …

Optimization of Pavement Marking Performance
<p>Pavement markings must perform on a variety of asphalt and concrete surfaces. Surface preparation can also affect a markings initial visibility and long-term performance. Therefore, there is a need for information on the performance of pavement markings under many conditions including type of …

High-volume recycled materials for sustainable transportation infrastructure
… The main focus was to develop mixtures for rigid pavement construction. A variety of fine and coarse recycled concrete aggregates (RCA) were investigated. The feasibility of replacing 50% of Portland cement with industrial by-products and supplementary cementitious materials (SCMs) was also …

Effect of pre-stressing on the durability of portland cement concrete
… concrete is extensively used in bridge construction and that it holds potentialities for eventual use in pavement construction, and that methods must be investigated to utilize an otherwise rejected aggregate which cannot be used for its poor performance under natural weathering, it has …

Early Age Assessment of Cement Treated Materials
… allowed to cure for a period of time before the pavement can be opened to traffic. The purpose of this research was to evaluate the utility of the soil stiffness gauge (SSG), heavy Clegg impact soil tester (CIST), portable falling-weight deflectometer (PFWD), dynamic cone penetrometer, and …

Performance Analysis and Modeling of Pavements with a Cold Central Plant Recycled Base under Accelerated Loading Testing
… to save material, money, time, and energy in pavement construction and rehabilitation. The objectives of this thesis were to: (1) perform an instrumented verification analysis, (2) evaluate the response and performance of two pavement configurations with a CCPR base layer through accelerated …

Pavement sustainability optimization using quarry by-products and geosynthetics
Sustainability has become a major concern in the construction industry, especially highway construction. In the U.S, significant effort is being exerted to quantify the environmental emissions associated with construction and production of materials used in pavement construction. The increased …

Investigating and Understanding the Effects of Reclaimed Asphalt Pavement and Shingles on the Rheology and Performance Grading of Asphalt Cement.
The incorporation of Recycled Asphalt Pavements (RAP) and Shingles (RAS) into neat asphalt binder is a useful development towards environmental sustainability apart from its economic savings benefits, which comes as a relief to the finances of the transportation sector. Recycling of pavements …

Prediction of in-situ asphalt mixture density using ground penetrating radar: theoretical development and field verification
… important to the performance of flexible pavements: density that is too high, or too low, may cause early pavement distresses. Traditionally, two methods have been commonly used for in-situ asphalt mixture density measurement: laboratory testing on field-extracted cores, and in-situ …
