Principles of road maintenance (2a)
Types of operations
Routine service:
The aim of routine service is to ensure the required service level of
roads.
The works include: patching, crack sealing, strip and spot surface
dressing, shoulders ordering, grass mowing, gravel road planning,
brushwood cutting, cleaning of ditches, maintenance of culverts,
marking of roads, maintenance of traffic signs and marker posts,
winter service works.

Principles of road maintenance (2b)
Types of operations
Periodic service:
The aim of periodic service is to rehabilitate the worn-out parts of the
road.
The works include: repair of the embankment, dust binding, digging
of new ditches, construction of culverts, installing of new traffic
signs and boards and safety barriers, repairs of gravel roads in
small extent; surface dressing of paved roads. The works are done
by the yearly Bill of Quantities fixed before May, 01.
Retain repairs:
The aim of retain repairs is to keep gravel roads in good condition
until the renewal.
The works are done by the yearly Bill of Quantities fixed before
April, 01.

Requirements for the state of roads (1)
• Both in summer and winter the requirements for the state of
roads depend on the importance of the road and traffic flow;
• There are 4 service levels;
The requirements for the 4th level are most strict and for the 1st
level the modest.
6
Requirements for the state of roads (2)
Summer service levels
paved roads
gravel roads
Winter service levels
unified for paved and gravel roads
7
1st service level. Paved road in summer
8
3d service level. Paved road in summer
9
Requirements for the state of roads (3)
Summer service
Paved roads:
• condition of pavement (evenness [IRI], cracks, pot holes, ruts);
• road security (road markings, sign posts);
• range of side visibility;
• performance of summer service works (mowing).
Gravel roads:
• condition of surface (cross-fall, evenness, ruts);
• range of side visibility;
• performance of summer service works (mowing).
10
Requirements for the state of roads (4)
Winter service
• general state of road surface (snow-clearing, anti-skid
treatment);
• assurance of required friction coefficient;
• maximum permitted thickness of snow layer (dry snow, wet
snow, sleet, salt-snow mix) on the road;
• unevenness of road surface caused by snow or ice (ruts, trafficthickened snow).

General principles of maintenance contract (1)
•
summer and winter service enclosed into the same contract;
•
duration of the contract 4-5 years
•
integral parts of contract: routine and periodic service; + retain repairs
(since 2007);
•
routine service – amount of work given must ensure the required
condition of the road (service level). Paid performance-based;
•
periodic service, retain repairs – prescribed amount of works must be
carried out. Paid by unit prices;
8-9 years;
13
General principles of maintenance contract (2)
•
payment for maintenance works is accomplished in monthly basis in
accordance with the “Financing Schedule” (annex to the contract);
•
deductions from payable sums are made due to low quality of
performance, discovered during supervision;
•
customer has right to collect penal fine if the maintenance
documentation is not submitted in due time (detailed in contract);
•
The prices of operations and works change every year in accordance
with the Road Operation Price Index (in former contracts Construction
Price Index) published by the Statistics Estonia;
14
Supervision of road operations (1)
•
Road Operations Supervision Guide (approved by the Directive of
Director General of ERA);
•
Contractors are obliged to devise and implement the internal plan for
quality assurance of maintenance works
Supervision of road operations
Contractor’s supervision
Customer’s supervision
15
Supervision of road operations (2)
•
Two categories of supervision :
– daily supervision: selective checking whether the service level is
obtained;
– monthly supervision: checking if the road conditions fulfil the
requirements to the specified service level and maintenance
contracts in the whole area
16
Further activities
Flexibility by making a
new contract
1.
Enlistment of shortcomings,
drawbacks, imperfections discovered
during supervision
2.
Analysis of these demerits: who’s to
blame? – contractor or customer?
3.
Working out measures in order to
make contractors’ work more efficient
and economically optimal
4.
Implementing these measures
1.
Enlistment of new shortcomings, drawbacks,
imperfections discovered during supervision
etc.
