What is the most important for consistent compaction of asphalt mix? The mix is hotter in temperature The mix is colder in temperature The mix is uniform in temperature Temperature of the mix does not affect compaction - ✔✔The mix is uniform in temperature Referring to general stationing guidelines, R1 would be ____ than R Closer to centerline Closer to outside shoulder Closure to the inside shoulder Both A and C - ✔✔Both A and C While using the rolling straightedge, if the needle goes in the red zone indicating an unacceptable high spot in the section, you then - ✔✔Mark the pavement where the needle first goes into the red zone and place another mark where the needle leaves the red zone and continue For bridge approach slabs, the 15 foot manual straightedge should be set so ____ is on the bridge deck. 1 inch Exactly 1/2 of the straightedge The entire straightedge None of the above - ✔✔1 inch
The lane width Height from the end of the level to pavement surface The diameter of the bubble in the level - ✔✔Level length and height from the end of level to pavement surface When paving 5 foot wide shoulders or open-graded friction course FC-5 cores should be taken at the frequency of... 1 per 100 feet 5 per lot 5 per sub lot 1 per 1000 feet None of the above - ✔✔None of the above Density cores for acceptance testing are not required for: Mix less than 1 inch thick Shoulders less than 5 feet wide Acceleration and deceleration lanes less than 1000 feet in length Ramos less than 1000 feet - ✔✔All of the above If a core sample is needed just after paving then Coring can be done immediately Let the pavement be cool to the touch before coring Run extra water from the core rig while coring
Wait until the pavement surface temperature has cooled below 160 degrees before coring - ✔✔Wait until the pavement surface temp has cooled below 160 degrees before coring Align the core barrel over the marked sampling location so that It is a slight angle to the pavement It is perpendicular to the truck bumper It is perpendicular to the pavement surface The top of the barrel is tilted slightly towards the truck - ✔✔It is perpendicular to the pavement surface How should asphalt cores be stored when transporting in hot weather? Stacked on top of each other in a box for each project being sampled By standing them upright in a cool shady location By lying them flat in the back of a truck In the cab of a un air conditioned truck - ✔✔By standing them upright in a cool shady location Asphalt placed when the mix temperature is too low can cause which of the following problems? Texture problems Density may not be achieved Ride or smoothness problems All the above - ✔✔All the above What is the most accepted way to take the temperature of the hot Mix asphalt in the truck?
