MEMBER NEWS/NEW MEMBERS TACA Welcomes New Members ember m T.G. Blair Gulf Coast Concrete and Shell Inc. 281-238-8883 4713 Ransom Rd. Richmond, TX 77469 that concrete durability will be easier to obtain. Another change made by this special provision will be to expand the concrete mixture design options available to a concrete producer, speciﬁcally by allowing the producer to use a dense aggregate gradation in the mixture design. An important element of this change is its optional nature. TACA Speciﬁcation Committee members provided feedback and information about the differences in statewide material availability that could make mandatory use of a dense aggregate mixture very expensive in some areas of the state. While TxDOT has acknowledged expertise in designing, contracting, inspecting and operating transportation facilities, we are not the experts in the speciﬁcs of manufacturing cement or mineral and chemical admixtures, processing aggregate or supplying ready-mixed concrete. Thus, by getting industry review and comment on changes that we believe will improve our concrete speciﬁcations, we can have greater conﬁdence that the changes will actually improve the cost-effectiveness of all of our concrete products. For more information about TxDOT concrete speciﬁcations,please contact Lisa Lukefahr at (512) 506-5858 orelukefa@dot.state.tx.us. Editor’s Note: Ms. Lukefahr is the Manager of TxDOT’s Rigid Pavements and Concrete Materials Branch. She is also a member of TACA’s Speciﬁcation Committee and works closely with industry and academic experts as a member of the Concrete Pavements Working Group.
