Introduction of the assignment

The assignment is divided to two parts:

Part A

Will include: Drainage design with proposal alignment together with drawings / drainage calculations.

Part B

Will include: Traffic calculation, pavement design with carriageway, specification and CDM/environmental/economic point of view.

I will present my report as whole however there will be comment next to the title of part whether it belongs to part A or part B.

1. Traffic Calculations

Using traffic assessment HD 24/06

Given data/information:

Single Carriageway (S2)

Life = 20 years (New)

AADF = 5000

OGV1 = 400

OGV2 = 550

PSV = 200

The factor used to calculate the design traffic (T) are as follows:

-Commercial vehicle flow at opening (F)

-Design period (Y)

-Growth factor (G)

-Wear Factor (W)

-Percentage of vehicles in the heaviest loaded lane (P)

a)      F = 400 + 200 + 550 = 1150 cv/d

550/1150 = 47.82 % ≈ 48% OGV2

b)      We know Y = 20

c)       Wear Factor for CV classes and categories from table 2.3

Thus => OGV1 + PSV for new WN= 1.0

               OGV2 for new WN=4.4

d)      Extracted growth factor (G) values assuming 1997 growth table:

For design period (Years)…………………………………………………………20

OGV1 + PSV…………………………………………………………………………..1.09

OGV2…………………………………………………………………………………….1.27

e)      It is single carriageway so we are using P as 0.97

Finally our T is calculated below in the table:

Design Traffic (T) = Total weighted annual traffic x Y x P x 365 / 1000000 =

                               = (3727.4 x 20 x 0.97 x 365) / 1000000 = 26 .393 ≈26 MSA

2.Drainage Design

a)Introduction

The proposed solution is shown on the map below. The new road is starting from Markeaton Street and will be connect with Queensway . This part of the assignment will  provide a proposed drainage system based on proposed road alignment and the actual level from field.

We are creating controlled system. The water is guided by pipes to a suitable outlet. The map is consistent  with the direction of the north and the contours of existing ground level are on. The proposed single carriageway is  268.10m long and  is 7.3m width, more details are shown on the drawings attached with the assignment.
