DETERMINING ASPHALTIC CONCRETE PAVEMENT STRUCTURAL PROPERTIES BY NONDESTRUCTIVE TESTING. The high-volume data collection capabilities of modern nondestructive testing equipment require an analysis method which is capable of rapid backcalculation of pavement layer moduli in a production mode of data by:   Nondestructive testing provides ideal means to test pavement structure in a rapid and convenient manner. In last few years, significant development has taken place in this field. This paper, presents some of the major conventional as well as emerging nondestructive evaluation methods for in situ structural assessment of asphalt by: Non-destructive testing is used to test functional and structural properties of the pavement. This section discusses the use of non-destructive testing to evaluate the functional properties and the next section discusses its use for structural properties. Functional properties routinely evaluated include. Anchor: #i Section 5: Destructive Evaluation of Pavement Structural Properties Anchor: #i Introduction. Trenching, coring, and augering have been used in forensic and routine pavement evaluation to determine the source of the problematic layer or layers and acquire materials for further laboratory testing.

Normally 50 years for concrete and 30 years for asphalt. 3. Material properties for structural design which distinguishes concrete pavement, is the type of joint used to control cracking and whether or not steel dowels are used in the joint for load transfer. Low stability in asphalt concrete may lead to various types of distress in asphalt pavements (Tigdemir et al., , ). The stability of asphalt concrete pavements depends on the stiffness of the mix, bitumen content, softening point of bitumen, viscosity of bitumen, grading of aggregate, construction practice, traffic and climate (Cooper. Deflection test - a non-destructive method to determine the overall structural capacity and properties of existing pavement.   Pavements are engineered structures essential to transportation, commerce and trade, and everyday life. In order for them to perform as expected, they must be designed, constructed, maintained, and managed properly. Providing a comprehensive overview of the subject, Pavement Engineering: Principles and Practice, Second Edition covers a wide range of topics in asphalt and concrete pavements.

Section 39 Asphalt Concrete General. Sect “Asphalt Concrete,” of the Standard Specifications provides material and construction requirements for hot mix asphalt (HMA) including Type A, rubberized hot mix asphalt-gap graded (RHMA-G), open-graded friction course (OGFC), minor HMA, and hot mix asphalt with warm mix asphalt (WMA) additive technology. Asphalt concrete pavements are inherently nonhomogeneous in nature and exhibit instability (incompatibility) which can have serious consequences for mechanical properties of a roadway asphalt mix (Masad et al., ). Property gradients are most severe across the thickness of the asphalt concrete layers. Pavement Engineering will cover the entire range of pavement construction, from soil preparation to structural design and life-cycle costing and analysis. It will link the concepts of mix and structural design, while also placing emphasis on pavement evaluation and rehabilitation techniques. State-of-the-art content will introduce the latest concepts and techniques, including ground 1/5(1).
