1 This historical pavement data is provided for information only. It includes a history of pavement work that has been contracted through the NDOR Construction letting process. This history is generalized to depict the primary strategy (or strategies) used for a given construction project and may not encompass all work that was performed to all sections of a roadway. Furthermore, it does not include any work performed by NDOR Maintenance forces. Pavement Design Acronyms & Definitions Definitions B.S.B.C.

Used in the same type of projects as type This mix is composed of not less than 30% crushed rock, crushed mineral aggregates which contain no more than 20% naturally occurring fine aggregates retained on the No. 10 sieve and mineral filler if required, 60% maximum limestone permitted. Used for the same type of projects as type 14. 4R This mix is identical to type 4 except that a (RAP) material is used to supplement the virgin aggregate. Used in the same type of projects as type This mix is composed of a combined mineral aggregate, 60% maximum limestone permitted. Used for the same type of projects as type 17. 7R II IIR A A Special AX AX Special Q This mix is identical to type 7 except that a (RAP) material is used to supplement the virgin aggregate. Used in the same type of projects as type 17. This mix is composed of mineral aggregate No. 2-A, mineral aggregate No. 5 (fine sand) and mineral filler. This mix is identical to type II except that a (RAP) material is used to supplement the virgin aggregate. This mix is composed of crushed rock, mineral filler and 3-A crushed sand gravel. This mix was used as both a base and surface course. This mix is composed of crushed rock, mineral filler and 3-A crushed sand gravel. This mix was used as a base course. The gradation of the crushed rock was slightly coarser and the percentage content of crushed rock in the mix higher than the A mix. This mix is composed of crushed rock, fly ash and mineral aggregate. It was used as both a base and surface course on the interstate. This mix is composed of the same material as type AX only this mix has a higher percentage of crushed rock. It was used as a base course on the Interstate. This mix is composed of crushed quartzite or crushed granite. This was used as a surface layer on the Interstate.

21 RQ MQ CC, CC1 & CC2 RCC RAX RAX Special SMA SUPERPAVE SPS This mix is identical to type Q except that a (RAP) material is used to supplement the virgin aggregate. Used on same type of projects as Q. This is an open graded mix composed of quartzite or granite gravel sand aggregate and mineral filler. Used on the surface layer of the Interstate. These mixes are composed of crushed concrete, 3-A sand and mineral filler. This mix is composed of (RAP), approximately 82% crushed concrete and 18% 3-A sand gravel. Used as a base course on the Interstate. This mix is identical to the type AX except that it has a RAP material added to supplement the virgin aggregate. Used in the same line as type AX. This mix is identical to the type AX Special except that it has a RAP material added to supplement the virgin aggregate. Used along the same lines as type AX Special. Experimental European Mixture Stone Mastic Asphalt composed of crushed rock, 3A crushed sand gravel and mineral filler. Used on high traffic volume roads. This is a mix design system for specifying asphalt binders and mineral aggregates, developing and analyzing asphalt mixtures and establishing pavement performance prediction, based on cumulative equivalent single axle loads. In general SP4 and SP5 will be used on mainline pavements and SPS will be used on shoulders. This is a Surfacing for Paved Shoulder mix. This mix uses PG (52-34 as of ) at a content to yield a target air void of 1.5%. It promotes the use of RAP at a content of 35 to 50% and thus reduces the amount of added binder and aggregates by as much as half. It contains no lime. GGCRM This is a Gap Graded Crumb Rubber Modified mix. Placed as a surface mix, usually 1.5 to 2.5 in thickness. This has the resemblance of a SMA (Stone Mastic Asphalt) mix. It is a high binder, rut and crack resistant surface which is still in research and development stages. Used on high volume roadways. GGCRMLV LC This is a Gap Graded Crumb Rubber Modified Low Volume mix. Placed as a surface mix, usually 1.5 to 2.5 in thickness. This has the resemblance of a SMA (Stone Mastic Asphalt) mix. It is a high binder, rut and crack resistant surface which is still in research and development stages. Used on low to medium volume roadways. This mix is used as a type of SAMI (stress absorbing membrane interface). It is a fine graded mix. This leveling course is intended to slow down reflective cracking from the existing pavement and to provide an impermeable layer to resist the flow of water in the asphalt mix. This mix uses PG (64-34 for non-interstate as of ) with a high binder content to produce a lower air void content (2.5%).

22 RLC OGFC-CRM HRB SPL SPR This mix is used as a leveling course for HLSS, FDR, and overlay projects. This mix is the same gradation as an LC but uses standard PG binder types and contents, and targets regular mainline volumetrics. This is an Open Graded Friction Course mix. Placed as a surface mix, usually 1 to 1.5 in thickness. This is coarser than a regular OGFC and contains higher binder amounts. This mix uses binder that is modified with crumb rubber. Provides a high friction, drained and quiet pavement section. Used on mainline roadways and ramps. This is a High Rap Base mix. It is a very fine graded, single aggregate mix used in lower lifts only. It contains a minimum 25% or 35% RAP as specified and a maximum 50% RAP. The mix contains no lime and a minimum 5.5% of PG (64-34 as of ) binder. It is a very stiff mix used on low to medium volume roadways. This Static Pressure Loading mix is a well graded Marshall mix. There is a fine mix and a course mix. The mixes are used primarily for camper pads, parking lots, lower lifts, and temporary pavement. RAP is not required but often needed to achieve the required 230 psi bearing capacity. It contains no lime and a minimum 5.2% of PG (64-34 as of ) binder. This is a coarse but well graded mix used in lower lifts on low to medium volume roadways and surface lifts on low volume roadways. It is a gyratory mix created to replace the SPL mix. It requires lime, has a minimum 20% RAP and minimum 5.0% of binder.
