(A) All commercial driveways will be hard surface, of either bituminous or concrete, from the edge of the mainline pavement to the county right-of-way line. Residential driveways shall be a paved, hard surface, or compacted aggregate from the edge of the mainline pavement to the county right-of-way line. Field entrances shall be compacted aggregate.
(B) Care should be taken in the design of parking areas and frontage roads to alleviate possible tracking of gravel or debris onto the mainline pavement.
(C) The cross slope or crown of driveways and turn lanes should be 2% for bituminous pavement or concrete pavement. A compacted aggregate shoulder is required adjacent to all commercial driveways and added lanes. The shoulder shall be constructed a minimum of four feet in width and six inches in thickness. The slope of the shoulder should be 6%.
(D) If the existing shoulder is bituminous, then the new shoulder should also be bituminous. The new shoulder should match the existing width with a slope of 4%.
(E) When a turning lane is required, the County Highway Department requires the added lane(s) be constructed out of the same material used for the mainline pavement, resulting in a homogenous pavement surface. The abutting edge of the existing mainline pavement shall have as smooth as possible interface with the new pavement, such as a saw cut.
(F) All materials and their placement should be in accordance with current INDOT specifications. Liquid asphalt shall be of the performance graded (PG) type. The required liquid asphalt shall be as shown below unless otherwise approved in writing by the County Engineer.
(G) Flexible pavement construction shall be constructed in accordance with the requirements of Section 402 of the Standard Specifications, with the exceptions as noted below. Materials shall comply with the requirements of Sections 902.01(a) and 904 of the INDOT Standard Specifications.
(1) Mixture type shall be selected using the following table:
Section 402 Mixture Type
|
Road Classification per the Thoroughfare Plan*
|
A | Minor Collector, Local |
B | Minor Arterial, Major Collector |
C | Major Arterial |
* From the Hancock County Comprehensive Plan, Chapter 151 of the Hancock County Code. All Multiple-axle truck traffic pavements shall use asphalt mixture Type C.
(2) Surface aggregate type: For Type A and B mixtures, the surface aggregate requirements shall meet the requirements for less than 3,000,000 ESAL in 904.03(d). For Type C mixtures, surface aggregates shall meet the requirements for less than 10,000,000 ESAL in 904.03(d).
(3) Compaction shall be in accordance with 402.15 for all mixture types. When directed by the County Engineer, core samples shall be obtained from the pavement for final acceptance in accordance with 401.16. The maximum specific gravity shall be supplied from the Certified HMA Producer in accordance with 402.02. The pay factors of 401.19 will not apply.
(4) PG Binder Grade: Asphalt binder grades are listed in the following table for Type A, B, and C mixtures.
Mixture Type | Mixture | 0% RAP | Up to 15% RAP | >15% to 25% RAP |
Mixture Type | Mixture | 0% RAP | Up to 15% RAP | >15% to 25% RAP |
A | Surface | 64-22 | 64-22 | Not allowed |
Intermediate | 64-22 | 64-22 | 58-28 | |
Base | 64-22 | 64-22 | 58-28 | |
B | Surface | 64-22 | 64-22 | Not allowed |
Intermediate | 64-22 | 64-22 | 58-28 | |
Base | 64-22 | 64-22 | 58-28 | |
C | Surface | 70-22 | Not allowed | Not allowed |
Intermediate | 70-22 | 70-22 | 64-28 | |
Base | 64-22 | 64-22 | 58-28 | |
(5) Acceptance will be based on Section 402.09.
(6) All sampling and testing shall be performed by a consultant/engineer approved by the Hancock County Highway and fees paid by the contractor.
(H) The following are the pavement sections that shall be used. All pavement shall be placed on subgrade that has been compacted in accordance with the INDOT Standard Specifications and all commercial and industrial driveways shall be prepared per Section 215, Chemical Modification of Subgrade Soils, of the INDOT Standard Specifications.
