Pro-Cast 30’ Rigid TL-3 MASH Barrier (with and without Spacers)

Report Number(s): Test No. P43166-01, P43152-02, P43173-01, P43153-01

Description: The Pro-Cast 30' Rigid TL-3 MASH Barrier was a temporary concrete longitudinal barrier designed to shield roadside hazards. The 30' Freestanding Barriers were 30.0 ft. (9.1 m) long, 2.0 ft (0.6 m). wide, and 2.7 ft. (0.8 m) high.   Each 30.0 ft. (9.1 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 thirty-six (36) #4 vertical bars, thirty-six (36) #5 loops, seventy-two (72) #5 angled loops, and six (6) #5 longitudinal bars down the length of the barrier. 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 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 seven (7) 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 30' Rigid TL-3 barrier was tested in 2 configurations:

1. Freestanding with no spacers
2. Freestanding with spacers
