This report documents two full-scale crash tests conducted in support of a study to investigate the safety performance of the Hawaii Department of Transportation's 34-in. Tall Aesthetic Concrete Bridge Rail system. The barrier system consisted of two 11-ft long concrete rails and three 22-ft long concrete rails anchored to the concrete tarmac. The expansion joint consisted of 24-in. long, No. 8 ASTM A615 Grade 60 steel bars that were casted into the concrete and inserted into a PVC pipe on the upstream side of the expansion joint. Test nos. H34BR-1 and H34BR-2 were conducted according to Manual for Assessing Safety Hardware 2016 (MASH 2016) criteria using Test Level 3 (TL-3) test designation nos. 3-10 and 3-11, respectively. In test no. H34BR-1, an 1100C vehicle impacted the bridge rail at a speed of 62.4 mph and at an angle of 25.7 degrees. In test no. H34BR-2, a 2270P vehicle impacted the bridge rail at a speed of 64.0 mph and at an angle of 25.4 degrees. Test nos. H34BR-1 and H34BR-2 resulted in the vehicles being safely redirected without violating any evaluation criteria. Therefore, test nos. H34BR-1 and H34BR-2 successfully met the TL-3 safety performance criteria defined in MASH 2016.
