The second paragraph is voided in its entirety and replaced by the following: The concrete mix design shall have a minimum cementitious material content of 470 lb. per cubic yard. The fourth and fifth paragraphs are voided in their entireties. Section , Curb Forms. This section is voided in its entirety. Section , Carpet Drag. This section is voided in its entirety and replaced by the following: Brush or broom finish. The surface of the pavement shall be finished with either a brush or broom for all newly constructed concrete pavements. Section , Tining Equipment. This section is voided in its entirety. Section , Job-Control Strength. The second paragraph is voided in its entirety and replaced by the following: Use a compressive strength of 3,600 psi or a lower job-control strength value proven to meet a 28-day compressive strength of 4,400 psi as correlated in accordance with Tex-427-A for 7-day job-control by compressive strength. Section , Table 1. The second row Flexural Strength is voided in its entirety. Section , Curb Joints. This section is voided in its entirety. Section , Curbs. This section is voided in its entirety. Section , Surface Texturing. This section is voided in its entirety and replaced by the following: Surface Texture. The surface of the pavement shall be finished with either a brush or broom for all newly constructed concrete pavements. It is important that the texturing equipment not tear or unduly roughen the pavement surface during the operation. Any imperfections resulting from the texturing operation shall be corrected to the satisfaction of the Engineer. a. Brush or broom finish. If the pavement surface texture is to be a type of brush or broom finish, it shall be applied when the water sheen has practically disappeared. The equipment shall operate transversely across the pavement surface, providing corrugations that are uniform in appearance and approximately 1/16 inch in depth. Section , Asphalt Curing. This section is voided in its entirety CSJ No. 17HGRCKPT

36 Section , Curing Class HES Concrete. This section is voided in its entirety. Section , Curing Fast-Track Concrete Pavement. This section is voided in its entirety. Section , Early Opening to All Traffic. This section is voided in its entirety and replaced by the following: Concrete pavement may be opened after curing is complete and the concrete has attained a compressive strength of 3,600 psi. Section , Fast Track Concrete Pavement. This section is voided in its entirety. Section , Pavement Thickness. The third and fourth sentences are voided in its entirety and replaced by the following: Conditioning of underlying surface. After the underlying surface has been placed and compacted to the required density, the area to be paved shall be trimmed or graded to the plan grade elevation and profile by means of a properly designed machine. The grade of the underlying surface shall be controlled by a positive grade control system using lasers, stringlines, or guide wires and depth shall be verified with a ruler by the Engineer on a 25 x 25 grid 24 hours prior to placement of concrete to ensure correct concrete depths. If the density of the underlying surface is disturbed by the trimming operations, it shall be corrected by additional compaction and rested at the option of the Engineer before the concrete is placed except when stabilized subbases are being constructed. If damage occurs on a stabilized subbase, it shall be corrected full depth by the Contractor. If traffic is allowed to use the prepared grade, the grade shall be checked and corrected immediately before the placement of concrete. The prepared grade shall be moistened with water, without saturating, immediately ahead of concrete placement to prevent rapid loss of moisture from concrete. The underlying surface shall be protected so that it will be entirely free of frost when concrete is placed. Section , Thickness Deficiencies Greater than 0.2 in. This section is voided in its entirety and replaced by the following: Thickness Deficiency Evaluation. An evaluation of the surface grade shall be made by the Engineer for compliance to the tolerances contained below. The finish grade will be determined by running levels at intervals of 25 feet or less longitudinally and all breaks in grade transversely (not to exceed 25 feet) to determine the elevation of the completed pavement. The Engineer will provide surveying services for evaluation of grade line elevations and cross sections. The Engineer will provide the Contractor with documentation of the evaluation within 7 business days after completion of the survey. (a) Lateral deviation. Lateral deviation from established alignment of the pavement edge shall not exceed ±0.10 feet. (b) Vertical deviation. Vertical deviation from established grade shall not exceed ±0.04 feet at any point. Any areas that exceed deviation requirements listed above shall be removed and replaced at the Contractor s expense. Section , Thickness Deficiencies Greater than 0.75 in. This section is voided in its entirety. Section , Pavement Units for Payment Adjustment. This section is voided in its entirety. Section , Ride Quality. This section is voided in its entirety. Section , Curb. This section is voided in its entirety. Section , Concrete Pavement. This section is voided in its entirety and replaced by the following: Concrete Pavement. The work performed and materials furnished in accordance with this Item and measured as provided under Measurement will be paid for at the adjusted unit price bid for Concrete Pavement of the type and depth specified in the plans. Section , Deficient Thickness Adjustment. This section is voided in its entirety. Section , Curb. This section is voided in its entirety CSJ No. 17HGRCKPT
