Report Number(s): Test No. P43202-01, P43203-01, P43222-01, P43198-01, P43201-01, P43223-01

Description: The Pro-Cast 20' Rigid TL-3 MASH Barrier is a temporary concrete F-shape profile longitudinal barrier designed to shield roadside hazards. The 20' Freestanding Barriers are 20.0 ft. (6.1 m) long, 2.0 ft (0.6 m). wide, and 2.7 ft. (0.8 m) high.   Each 20.0 ft. (6.1 m) barrier required a minimum 28-day compressive strength of 4,000 psi (27.6 MPa). The concrete barrier utilized steel reinforcement composed of ASTM A36 Grade 60 rebar and consisted of four (4) #5 loops, eight (8) #5 angled loops, six (6) #5 longitudinal bars down the length of the barrier, and twenty-two (22) #4 vertical bars. In addition, each barrier also had #5 reinforcement bars at each 4.0 in. (102 mm) diameter lifting thru-hole and an assortment of #5 rebar reinforcing the stake opening. The complete section reinforcement details are shown in Appendix C: Manufacturer Documents.   The barrier sections were connected to one another with ASTM A36 0.75 in. (19 mm) steel loops embedded in each barrier which were then interlocked with a 1.25" (32 mm) diameter by 24.5 in. (622 mm) long solid steel pins.   The barriers were set on an asphalt slab 6.0 in. (152 mm) thick. A total of ten (10) freestanding barriers were used. The barrier system allows for installation of a barrier limiting and protection spacer constructed of 24.0 in. (610 mm) high by 3.0 in. (76 mm) wide by 0.375 in. (10 mm) uniform density plastic with a minimum compressive strength of 6000 psi (41.4 MPa). If utilized, the spacers are placed on the ends of each barrier on the traffic side of the interconnecting pins. The spacer sits flush with the barrier if utilized.   The Pro-Cast 20' Rigid TL-3 barrier was tested in three (3) configurations:

1. Freestanding with no spacers
2. Freestanding with spacers
3. Pinned to asphalt with no spacers
