Draw an asphalt concrete pavement section consisting of an asphalt concretesurface layer, aggregate base, and subgrade. Show the locations of prime coat and chip seal.
An agency uses the following formula to determine pavement condition rating, PCR = 99.3 − 5.51 (5.0-ROUGH) − 1.59 LNALL − 0.221 AVGOUT − 0.0306 LONG − 0.531 TRAN, where we have the following. ROUGH = roughness measured by present serviceability rating (PSR), scale of 0 to 5 LNALL = natural logarithm of alligator cracking, ft per mile AVGOUT = outer wheel path rutting (all locations averaged), 0.01 inch LONG = longitudinal cracking, ft per mile TRAN = transverse cracking, number of cracks per mile And, present serviceability rating is determined as the following. PSR = 5e−0.0051118 · IRI − 0.0016027 A pavement section has the following distress data. IRI = 108 in./mi Alligator cracking = 110 ft/mi Average rutting = 0.20 in. Longitudinal cracks = 130 ft/mi Transverse cracks = 12/mi Determine the current PCR for this section. PCR = Now, assume a new roughness measurement is expected soon. When PCR falls below 60, the section will be scheduled for rehabilitation. Determine the new IRI…
An asphalt distributor having a 12 -ft long spray bar will be used to apply a tack coat at a residual application rate of 0.05 gal/sy. The road being paved is 24 ft wide and 2 miles in length. How many gallons of liquid cement for the tack will be required? How many gallons of emulsion tack are needed if the mixture is 70% liquid asphalt and 30% water?
Which Performance Grade asphalt binder would work best in resisting low temperature cracks and which would work best in preventing rutting? a) 58-22 b) 60-20 c) 80-35 d) 82-33
Define voids filled with asphalt for asphalt concrete.
Pavement grooving - is effective in providing skid-resistance and prevention of hydroplaning during wet weather. It consists of forming or cutting closely spaced transverse grooves on the runway surface, normally 1‚ÅÑ4 inch deep by 1‚ÅÑ4 inch wide and spaced 1 1‚ÅÑ2 inches apart. Although grooves can be formed while laying PCC pavement, HMA pavement (whether new or existing) requires grooves to be saw cut. This is very common on airport runways.
Pavement design has evolved tremendously in the past few decades. The approach indesigning pavements has changed from primarily empirical to mechanistic-empirical. Preparea short essay (up to two typed pages or equivalent, not including references) highlighting thisevolution in pavement design methods. (Notes: Make sure to cite references (TRB format)used to prepare this essay) Briefly describe the distresses in flexible and rigid pavements?

A CRCP has a crack spacing of 10 ft and a temperature differential of 56°F. Measured edge deflection by Dynaflect is 0.0007 in. By the Asphalt Institute procedure, determine the required thickness of asphalt overlay and check for whether undersealing is required.
Problem No. 1A flexible pavement for an urban interstate highway is to be designed using the AASHTOmethod to carry a design ESAL of 3 x 106. It is estimated that it takes about a week for water tobe drained from within the pavement and the pavement structure will be exposed to moisturelevels approaching saturation for 30% of the time. The following additional information is available: Elastic modulus of asphalt concrete = 450,000 psiResilient modulus of base material = 35,000 psiResilient modulus of subbase material = 15,000 psiCBR of subgrade material = 8(a) Consider designing the same pavement with only asphalt concrete and base layer (excluding subbase layer). Use the information provided in Problem 1. (b) Compare strengths and weaknesses of each design.
