		True
		False

2.	Generally pavement repairs with epoxy materials shall not be initiated unless the air and pavement temperatures are above 40 degrees F and rising.

		True
		False

3.	Epoxy resin type I, is used to bond hardened concrete and other materials to hardened concrete. It is used for cementing dowels in drilled and preformed holes and for pressure grouting of nonworking cracks.

		True
		False

4.	Epoxy resin type II, is used to bond freshly mixed Portland cement concrete (PCC) to hardened PCC.

		True
		False

5.	Epoxy resin type III, is used to bond skid-resistance materials to hardened concrete, and as a binder in epoxy resin mortars or epoxy resin concretes for repairing spalls and for filling non-working joints.

		True
		False

6.	Figure 1 shows :
